Rare improperly treated traumatic vertical atlantoaxial dislocation: A case report and literature review

BACKGROUND: Because of the severity and fatal outcome of traumatic vertical atlantoaxial dislocation (AAD), most patients may die in the early post‐traumatic period. The post‐injury management of patients with vertical AAD has been rarely reported. Improper treatment may lead to disastrous outcome and further aggravate the neurologic symptoms. CASE PRESENTATION: This report describes the perioperative management and outcome of a rare improperly treated patient with traumatic vertical AAD. The severe pulmonary infection of this patient prevented further surgery for vertical AAD. After placement of a halo vest, combined with effective antibiotic drug treatment, the patient's pulmonary infection was brought under control. The patient underwent atlantoaxial fusion using C1 lateral mass screws and C2 pedicle screws with the assistance of the halo vest. A computed tomography scan at 1 year follow‐up indicated that the bone graft was fused and the patient was able to walk independently. CONCLUSION: Skull traction is contraindicated in patients with traumatic vertical AAD. Application of a halo vest can be used for temporary fixation of the cervical spine and atlantoaxial fixation should be performed to maintain the stability of atlantoaxial articulation.
